Abstract: 1,110,127. Fluid-pressure apparatus. INSTITUT FœR WERKZEUGMASCHINEN. Oct.26, 1965, No.45376/65. Heading F1P. A device for producing pressure impulses in a liquid comprises a diaphragm 5 separating the liquid from a cylinder 2 in which slides a piston 11 arranged to hammer a stop 6, carried by the diaphragm, so as to deflect the diaphragm and cause a pressure pulse to be induced in the liquid. A spring 13 normally urges the piston 11 into sealing engagement with a seat 12 against the action of compressed air supplied through an inlet 10 to the small annular face of the piston defined by the seat 12 and a reduced diameter portion 9 of a piston rod 8. When the piston rod is upwardly displaced, air acts on the complete annular face of the piston and hence moves upwardly to hammer the stop 6. Near the end of the piston stroke an air outlet 14 is uncovered by the piston 11 and air admitted thereto operates a valve 15 to shut off the air supply to the inlet 10. The spring 13 then returns the piston 11 which connects the outlet 14 to the atmosphere through a port 16 whereby the valve 15 operates to re-establish the air supply to the inlet 10 in preparation for a subsequent operation.

Abstract: 1,210,211. Image intensifier tubes. NATIONAL RESEARCH DEVELOPMENT CORP. 11 Jan., 1968 [11 Oct., 1966], No. 45480/66. Heading H1D. In an image intensifier tube a component such as the photocathode or in a cascade image intensifier a dynode which is only mounted in permanent position after the tube envelope has been sealed is held in position by a locking member constituted by a bimetallic element. In Fig. 2, the bimetallic element 8 overlies a rebated aperture 6 in a metal plate 4. When the bimetallic member 8 is heated, e.g. by means of an adjacent electric heater, by r.f. induction heating or by irradiation with a beam of radiation admitted through an aperture 10 provided in the plate 4, the free end of the member 8 moves away from the plate 4 and a photocathode plate is manoeuvred into the aperture 6. On cooling the member 8 bears against the plate 4 and the inserted photocathode plate. A fixed retaining tag 7 overlies the opposite end of the aperture 6. The photoemissive coating is formed on the photocathode plate in a separate cell and the plate is subsequently passed into the tube envelope through the pumping stem which is then sealed off. In Fig. 4 a circular metal plate 11 with a circular rebated aperture 12 is used for mounting a dynode and the bimetallic element is a curved strip 14 carrying a tag 16 and anchored at one end by means of a bracket 15. For the purpose of r.f. induction heating the strip 14 may carry a metal flag.

A cartridge tube to contain semen comprises a plastics tube containing a plug at one end which may be used as a piston for the ejection of semen from the other end of the tube and which 'is formed from a mixture consisting of polyvinyl alcohol and elements capable of rendering the mixture porous, compressed axially within the tube. The elements may be polyvinyl alcohol granules, with or without cellulose ether granules, or polyvinyl chloride peals.' A quantity of the mixture is inserted in the tube at one end, compressed between plungers, and then caused to adhere to form a porous plug by subjecting the mixture to humid air. A solution containing semen is drawn in by applying a vacuum to the porous plug. The tube may be sealed at the opposite end to the plug by polyvinyl alcohol powder.

Abstract: 1382350 Moving band filter press ENVIROTECH CORP 11 Oct 1972 [12 Oct 1971] 46796/72 Heading B1D A filter press apparatus comprises a plurality of filter plates 14 stacked vertically in a frame 13 and having an endless filter belt 11 entrained between adjacent filter plates. The top surface 23 (Fig. 3) of each filter plate 14 acts as a support for the filter band and is formed with a drainage grid 24 leading to a filtrate outlet. The lower face of each plate 14 is formed with an annular slot 30 therein and this slot carries and annular ring 15 which is reciprocal into and out of the slot 30. When they ring is retracted into the slot the filter band 11 may be moved. When the ring is projected out of the slot it seals against the filter band support on the next lower plate and acts as a filter frame between the plates and defines a closed filter chamber 53 between the pair of plates. Liquid to be filtered is led into these chambers by feed manifold 55 and flexible hoses 43. After filtration the cake in chamber 53 is pressed by supply of compressed air to the. far side of a diaphragm 34 which divides the chamber 53, the compressed air entering via conduits 36. The reciprocal ring is forced out of slot 30 by the application of compressed air to the far side of diaphragm 40 attached to the ring and forming a closed chamber at the top of the slot 30. A three way valve is provided at the end of feed manifold 55 to allow the selective introduction of liquid feed, water (for cake working) and air (for cake drying). Cake is removed from each chamber by withdrawing the rings into the slots 30 allowing the filter band to be moved. Cake is scraped off from the band as it moves by knives 16. The filter band may be spray-washed in housing 21. Safety devices may be incorporated (Fig. 6 not shown) to detect buckling of the plates and thereupon switch-off the feed. A limit switch may be mounted on each frame to detect when the rings are in the withdrawn position and thereupon allow movement of the filter band.

In welding a tube to another member, e.g. a tube plate, by an internal and an external weld, the one weld is started almost immediately on the completion of the other. In a machine for welding stub tubes 9 to a header 10 the header is supported on wheels 11 of a trolley 12. The welding machine 8 is mounted on a beam 7 movable vertically by pneumatic rams 6 supported on a gantry 4. The machine 8 comprises a shaft 15, Fig. 2, rotatable by a motor 19 and carrying an internal welding head having a non- consumable electrode 26 and a bracket 43 supporting an external welding head to which a consumable electrode 48 is fed by rolls 49. Cables supplying current, water and shielding gases to the heads are coiled on a reel 61 on the shaft 15. The internal welding head is watercooled and carries an apertured diaphragm 31 permitting a limited flow of argon which is fed to the weld zone through a central passage 34. The external welding head has a curved electrode guide and contact tube surrounded by a curved nozzle through which carbon dioxide is fed. Cams 21, 22 on the shaft 15 actuate switches 23, 24 to control the welding cycle. The external weld may be made first with welding current increased in steps as the weld proceeds to compensate for heat build up in the work. The rotation is stopped after a small overlap and, after a pause during which carbon dioxide continues to flow, the internal weld is started with the use of high-frequency. Towards the end of the internal weld the current is gradually reduced. The machine is located during welding by a fitting 28 on the shaft 15 engaging within the stub tube 9.
